lMP ROVEMENT IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 200,877, dated March 5, 1878; application fil d August 27, 1877.

To all whom it may concern:

, Be it known that I, Ovens N. SGHOFIEL D, l of the city of Oshkosh, in the county of Winthe whole spring, from endto end of the spirals,

is inone leaf.

The object; is to secure a pliable spring affording the greatest amount of elasticityin the combination of the semi-ellipse and spiral with the least intricacy of construction.

In the drawings, Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a plan.

A is the spring, attached to the axle D in the usual manner. The spirals may be longer or shorter than shown, or may begin at or near the center of the spring at L.

B is the stay-arm, to which the box E may be attached. It is connected with the end of the spirals by a joint, 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combined semi-elliptic and double spiral spring A, constructed substantially as shown and described, for the purpose specified.

2. The spring A, in combination with the jointed stay-arm B, substantially as shown and described, for the purpose specified.
